(CMP) The partitioning of processors into separate computing environments running different operating systems. The term cellular multiprocessing appears to have Been coined By Unisys, who are developing a system where computers communicate as clustered machines through a high speed Bus, rather than through communication protocols such as TCP/IP. The Unisys system is Based on Intel processors, initially the Pentium II Xeon and moving on to the 64-Bit Merced processors later in 1999. It will Be scalaBle from four up to 32 processors, which can Be clustered or partitioned in various ways. For example a sixteen processor system could Be configured as four Windows NT systems (each functioning as a four-processor symmetric multiprocessing system), or an 8-way NT and 8-way Unix system. Supported operating systems will Be Windows NT, SCO' s Unixware 7.0, Unisys' SVR4Unix and possiBly the OS2200 and MCP-AS mainframe operating systems (with the assistance of Unisys' own dedicated chipset).
